ARTIFICIAL TOOTH.

Specification of Iietters Patent.

Patented Aug. 19, 1913.

Application filed March 6, 1913. Serial No. 752,433.

T 0 all whom. it may concern:

Be it known that I, THOMAS E. DIMELOW, a citizen of the Unit-ed States, residing at Philadelphia, in the county of Philadelphiaand State of Pennsylvania, have invented certain new and useful Improvements in Artificial Teeth; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to artificial teeth of the class having a flat back with,'an obliquely formed socket extending from said back toward the front of the tooth and which is adapted to be secured to a straight flat backing having a pin or pins projecting. therefrom at an angle to the longitudi nal plane of the same.

The object of the invention is to provide 7 simple and efficient means for attaching the backing-to the tooth whereby a large hold- Fig. 2 is a frontview of the backing plateemployed forming a part of this improved tooth; Fig. 3 is a perspective view of the fastening element used for connecting the backing to the tooth. V

In the embodiment illustrated a flat backing or plate 1 is shown having a longitudinally extending slot 2 in which is adapted to be inserted and secured a fastening element in the form of a staple 3 having a which is inserted in the slot 2 and held therein by solder and when in position the outer face of this reduced cross bar of the staple extends flush with or projects beyond the outer face of the backing as shown clearly in Fig. 1. The legs 5. and 6 of this staple are arranged obliquely to its back or cross bar 4 and the inner ends thereof forming shoulders 7 which abut against the inner face of the plate 1 as shown in Fig. 1. These obliquely disposed legs 5 and 6' are designed to be inserted in correspondingly arranged sockets 8 and 9 formed in a tooth' 10 and are secured therein by cement or' other suitable material in the usual manner. These sockets 8 a d 9 which are spaced longitudinally exten from the rear face of the tooth toward the front thereof at an oblique angle. These pin receiving sockets are in the same position; same angle and of the same depth in all relative teeth or those of a kind, and for thisreason the backing plate, for one tooth will fit any of therelative teeth therefor, thus making the teeth interchangeable.

The pins or staples are entirely independent of the backing plate and with the aid of the tooth, a staple is set in position and the bar thereof temporarily fastened to the plate after which operation the tooth is removed and the operator proceeds to finish the work on the bridge. About the last work to be done is to put the tooth back on the pins or legs of the staple and which is securely fastened to said legs by cement or other suitable adhesive material.

While I have described my invention with more or less minuteness as regards details and as being embodied in certain precise forms, I donot desire to be limited thereto unduly any more than is pointed out in the claims. On the contrary, I contemplate all proper changes in form, construction and arrangement, the omission of immaterial elements and substitution of equivalents as circumstances may suggest or render expedient.

I claim as my invention:

1. An artificial tooth having obliquely formed sockets, a backing having obliquely carried pins adapted to enter said sockets, said pins being in the form of an angled staple carried by said backing, the body portion or cross bar of said staple being reduced and said backing having a slot to receive the reduced portion of the staple.

2. An artificial tooth having spaced sockets, a backing having a slot therein, a staple having the cross bar thereof reduced and secured Within said slot, shoulders m hand in presence of two subscribing formed on the inner ends of the legs of said wltnesses. staple and adapted to abut against the inner face of said backing plate, the legs of said THOMAS DIMELQW' J staple being arranged obliquely and adapted Witnesses:

to fit in the sockets of the tooth. GEO. H. RAPBON, In testimony whereof I have hereunto set M. HAMBURGER.
